Application filed June 21, 1916. Serial No. 104,927.

To all whom it may concern:

Be it known that I, FREDERICK M. FURBER, a citizen of the United States,and resident of Revere, in the county of Suffolk and State ofMassachusetts, have invented certain Improvements in Blacking-Machines,of which the following description, in connection with the accompanyingdrawings, is a specification, like reference characters on the drawingsindicating like parts in the several figures. V

This invention relates. to machines for use in applying to boots andshoes various fluids, such as blacking, stain or sizing, referred tohereinafter generically as blacking. An object of the invention is toprovide improved means for applying blacking to the upper surface of thebottom portion of a shoe which projects outwardly below the rand crease.

Tn a more particular aspect, an object of the invention is to sheet animprovement in machines of the .type illustrated in my earlier PatentNo. 1,025,523, granted May 7 1912, in order to render such machines moreefl'ective in operation upon certain classes of work. Such machinesinclude a rand crease guide, usually consisting of a metal disk, whichserves to position the shoe during the application of blacking toportions of the surface as, for example, to the edge of the heel, andthe guide is depended uponto apply the required coat of blacking to theupper surface of that portion of the shoe which projects outwardly belowthe rand crease. While the rand crease guide is entirely satisfactoryfor this purpose upon most types of shoes, it has been found lessreliable where the bottom portion of the shoe projects out-. wardly fromthe upper to an unusual extent, as in stitchdown shoes. This inventionhas for an object, therefore, the provision in such machines of moresatisfactory means for performing the blacking operation heretoforeperformed by the rand crease guide.

To the above and other ends, a feature of the invention consists innovel means comprising a rotatable brush for applying blacking to theupper surface of that portion of a shoe which projects below the randcrease.

by the sole securing stitches, and remains in effective engagement withthe work notwithstanding slight variations in the angle at,

which the work is presented to the machine. The effective operation ofthe brush is further insured, in the construction shown, by thearrangement of the bristles in such manner as to project at an angle tothe surface to be treated. In the illustrative embodiment of theinvention, moreover, the brush is mounted upon a rand crease guide whichserves the usual purpose of positioning the shoeand also protects theupper from contact with the brush.

A further feature of the invention consists in a novel combination ofmeans for applying blacking to the edge and to the upper surface of theprojecting bottom portion of a shoe. The construction shown comprisestwo brushes, one rotatable across the edge of the bottom portion of theshoe and the other rotatable longitudinally of the rand crease, withmeans for preventing deflection of either brush through engagement withthe other. This construction is of particular utility for treating theheel portion of a shoe and is accordingly illustrated as applied to thisuse, but it should be understood that the invention is not thus limitedin its application and that the term heel, as used herein forconvenience todesignate the work to be treated, is generally of broadsignificance and except where obviously required by the context is notto be regarded as implying a limitation with respect to any particularportion of the shoe bottom.

The above and other features of the invention, including certain detailsof construetionand combinations of parts, will now be described withreference to the accompanying drawings and pointed out in the claims.

In the drawings:

Figure 1 is a perspective view of a portion of machine of the samegeneral type i as that shown in my prior patent, with the constructionof the present invention embodied therein, and

Fig. 2 is a plan view, partly in section, of a portion of the mechanismshown in Fig. 1.

An important advantage of a brush for thisdi i The machine comprises abrush 2 mountpurpose is that it is readily conformable tofifijied on ashaft 4 and rotatable to apply blacksurface irregularities such as maybe caused.

ing to the edge of the projecting bottom portion of a shoe, such as theheel cm, Fig. 2, and a rand crease guide 6 mounted on a shaft 8 androtatable in a plane substantially perpendicular to the plane ofrotation of the brush 2, these parts being arranged in substantially thesame relation as in the machine shown in my prior patent and operatedthrough connections not illustrated herein in detail but fully shown anddescribed in said patent, which may be referred to for more completeinformation with reference to details of the illustrative machine. Theguide 6 is thus arranged to rotate longitudinally of the rand crease andpositions the shoe in such relation to the brush 2 as to cause the brushto wipe across the edge of the heel.

The guide 6 is substantially 'frusto-conical in shape and in theconstruction herein shown is formed to provide inner and outerconcentric portions 10 and 12 with their outer edges lying substantiallyin the same plane perpendicular to the axis of the guide. Between thetwo portions 10 and 12 is mounted a brush 14 which may have any desiredform and is shown herein as comprising a plurality of tufts of bristlessecured firmly in position in the space between the two portions 10 and12 as by means of a wire 16 extending through holes 18 in the portion ofthe guide '6 which connects the two portions 10 and 12. The brush 14 isthus in position to engage and apply blacki ng to the upper surface ofthe projecting bottom portion of a shoe simultaneously with theengagement of the brush 2 with the edge of the heel or like part.

Blacking is supplied to the brush 14 and to the outer edges of bothportions 10 and 12 of the rand crease guide by means of a disk 20' whichmay rotate in a suitable reservoir for blacking in the same manner as inthe machine shown in my prior patent. The portion 12 of the guide isthus effective in the same manner asthe crease guide in the earliermachine to apply blacking in the very bottom of the rand crease, whilethe brush 14; engages the considerable eX- tent of surface on thatportion of the shoe which projects below the crease, the portion 12serving also to protect the upper of the shoe from contact with thebrush 14.

The portion 10 of the guide serves to guard the brush 1-1 againstdeflection through engagement with the brush 2, this function.

being of particular importance in case the brush 2, as in theillustrative construction, is considerably larger than the brush 14,although the member 10 is in position to act as a guard to prevent thedeflection of either brush by engagement with the other. The portion 10of the guide has also the function of transferring to the brush 2 theblacking deposited thereon by the disk 20, the brush taking up theblacking as it wipes over this portion of the guide and applying theblacking to the edge of the heel.

The manner of operation and the use of the illustrative machine will beclear from the preceding description and require no further explanation.

Having described the invention, what I claim as new and desire to secureby Letters Patent of the United States is:

1. I11 a machine of the class described, the combination of a rotatablebrush having bristles projecting in oblique relation to its axis forapplying blacking to the upper surface of that portion of a shoe whichprojects below the rand crease, and means for protecting the upper ofthe shoe from contact with said brush.

2.

3. In a machine of the class described, the combination of a rotatablerand crease guide having a flaring portion shaped for engagement on oneside with the upper of a shoe above the rand crease, and a brush carriedby said guide on the opposite side of said upper engaging portion forapplying blacking to the upper surface of that portion of the shoe whichprojects below the rand crease.

4:. In a. machine of the class described, the combination of a rotatablerand crease guide having inner and outer concentric portions arranged toprovide a space between them and means'secured to the guide between saidinner and outer portions in position to apply blacking to the uppersurface of that portion of a shoe which projects below the rand crease.

In testimony whereof I have signed my name to this specification.
